LOADING-HATCHWAY FOR SHIPS.

Specification of Letters Patent.

Patented Nov. 19, 1907.

Application filed June 19. 1905. Serial No. 266,082.

To all whom it may concern:

Be it known that I, JEP CLosTER, subject of the German Emperor, andresident of Apenrade, Germany, have invented certain new and usefulImprovements in Loading- Hatchways for Ships, of which the following isa specification.

This invention relates to ships hatches and especially to cargo-portsfor cargo ships and its object is to provide a hatch of this kind which,owing to its special construction and great length, allows of very longobjects such as planks railway rails and the like being very easilyloaded and stowed away nearly up to under the deck of the ship.

In the annexed drawings, Figure 1 shows a side elevation view of theimproved hatch- -way or cargo-port, while Fig. 2 is a plan view of apart of same.

WVhen long objects are to be introduced into the cargo room of ships,the cargo-ports or hatchways must have a very great length. This lengthof the hatches must however not exceed a certain extent as otherwise thetransverse connections of the deck and especially the deck beams wouldbe interrupted or cutaway on too long a distance.

The object of this invention is to reestablish, at leastto a certainextent, the transverse connections of the ship which have been reducedby a very great length of the hatchway. To this end, the longitudinalflanges b of the hatehway are shaped in such a manner that their heightis greater on a certain distance in the middle of their length than thatof the end flanges, this higher part of the end flanges being parallelto the deck thus affording convenient place for mounting upon them aplatform a extending across the hatchway. This platform is thereforesituated at a higher level than the upper edge of the end flanges(transverse ones) of the hatch and the upper edges of the longitudinalflanges of the hatchway are sloping on both sides from their highestparts, supporting the platform to the end or transverse flanges. It iseasily seen that the platform a as Well as the lateral flanges 11 of thehatchway must have the necessary strength for insuring a sullicientlystrong transverse connection of the lateral parts of the ships deck. Theplatform a may be used for supporting windlasses c and (1.

Having now fully described my invention, what I claim and desire tosecure by Letters Patent is:

In a ships hatch or cargo-port the combination with the end transverseflanges, of longitudinal flanges each of the upper edges whereof have attheir middle parts a higher part arranged parallel to the ships deck,while the other parts of the said lateral flanges are sloping on bothsidse from these higher parts towards the extreme transverse flanges ofthe hatch and of a transverse platform arranged on and rigidly securedto the said higher parallel parts of the side flanges of the hatch,substantially as and for the purpose set forth.

JEP CLOSTER.
